HONZL that I, FRANK L. SESSIONS, e. of the United States, residing ct in the county of Franklin and so, have invented certain new and I Wements in Fuses and Fuse- Boxes, of which the following is a specifics.- tion, reference being had therein to the sccomp-stnyiog drewing. My invention relates to uses or cut-outs. It has for its object to produce a. fuse box provided with sdjustsbie contact devices adopted to ztcconn'nodst e fuses of varying coiiitcct-csnying capacities, which fuses differ in thickness and length.

in the drawings, Figure 1 is s. perspective View iookmg into a fuse ho): embodying my improvements and showing use in position. Fig. is e vesticei section, taken on the line 2 2 of Fig. 3, the fuse being removed. Fig. 3 is ahoi'izontsi section tekcnon the time 3-3 of Fig. 2. Fig. 4 shows 9. Contact plate in side and end elevation. Fig. 5 shows :1 spac ing strip or piste in. side and end elevation. Fig. 6 shows the insulating base plate in side end end elevation. Figs. 7, 8, and Q are views of one of the binding posts.

In the drawings, A represents a. fuse box or inciosure constructed ofv soitsbie insulating materiel and adapted to be supported in any desired position by brackets 05 attached to the back Wall thereof: Dctschztbiy secured to the book Wei of the box is an insuhtting biock or base B to which the contact devices, represented as it whole by B, are attached.

The hose B near either end is provided with s series of centrally arranged apertures 2 which are prefercbiy ski in Kine with eech other. The back Wall is grooved or recessed immediately adjacent to each of said series of apertures, as indicated at 2, to fiGCOZDXIlO- date the heads of the bolts 3, which extend through said apertures end eye adapted to secure the binding posts 4 to the hssc piste B. By providing the base with. s series of apertures, as shown, the contact devices or fuse-cenying eiemcnts, comprising the bil'id' mg posts and the contact members for fuse terminals, may be adjusted toward 01" from each other according to the Ecogth oi the fuse to be used by inserting the bolts 3 through the proper apertures of each seiies.

5, 5, indicate the contact members or forks between which the terminals 0, c, of the 53 cartridge fuse C are supported. The contest sorted between ti contact mm members preferably sepembie penile! pa. which is it good condoc o of eiecti'ici: removchiy secmued to the projection c o? the binding post a: by clamping cits 7, 7. 8 indicates oonoiiisrstively thi spacing pistes adapted to be tween the contact members 5, 5. new their inner ends and provided with 9 through which pass the bolts 7, the said boits being adapted to bind the said contact memhers end spacing pistes together. To adjust the s see or distance between the contact mem ers, the bolts 7 ere removed and the desired numbc' oi spscing pistes 8 shown in Fig. These parts ei'e bound together in eiectsicot 0011"! each other end with the binding the cismping bolts '7. 3

The 55sec C may he of any do size end the contact mess ing eicments 5, spend with end to recs "ve ti fuse. I prefer, however, a as shown in the drawings, hit from eithei' end thereof s fist 7 contact terminal above referred. to c. i side Weiis these teti'ninsis pi ie parade and fist, and adapted to i between and. to he fiieioi gt e11 I k psrsiiei Waits ct one of the cont...ct momb It Wii be noted that the insertion ciiid v: draws of c. fuse from the contact membeis resdiiy sccompiished in View of tIl"tI ;{6- merit of the parts of the said contect mem hers end the construction of the fuse. The operator simpiy needs to grip the fuse me? its center and force its terminate between pistes of the contcct members in. order to properly position the fuse.

I have found it desirableto illSUYO the proper Positioning of the binding posts the case piste B end their proper eii'ne with esoh other, to provide detachable g 1 which see sdapted to he insei'ted is hoies 11 in the binding posts and to L the watts of the hoies H in the hes-e iiiete. These holes 1V is the hose piste cm ranged in sets on to the hcies 2 at the cent end of the base piste to iHSLEZt when the hinding: post st that end of vice is connected to the piste time one of the holes 2, it can. swung s; amie of its connecting; liott 3 until the through the binding post registerswith'one of the holes 11 and a pin ii may then be dropped into place, insuring that the binding posts will be properly positioned. 11 is a screw fitting the threaded outer end of the hole 11 and adapted to retain the pin 11 in" position. T he conductors leading to the binding posts 4, 4, preterably enter the box through elongated openings 10, 10, in one side wall of the box and near either end thereof, these elongated openings permitting the conductors to move longitudinally within the box to permitthe adjustment of the contact devices therein.

It will be noted that the mechanism embodying my improvements is capable of adjustment longitudinally to accommodate various lengths of fuses, and that the fuse-carrying contacts are each in themselves laterally adjustable to accommodate various Widths of fuses.

I have found the lusecarrying mechanism embodying n v improvements to be of great importance Wlult the loads on the circuits m which the fuses are inserted, vary considerably, and Where it is advisable and often necessary at different times to usc'iuscs of different capacities.

hat I claim is 1. A fuse-carrying device comprising a base plate, a pair oi fuse-carrying elements, and means for securing each of said 'l usccar rving elements to said base plate in various positions longitudinal of the plate.

A t'use-carrying device comprising a base plate, a pair of time-carrying contacts each consisting of a pair of plates ad aptcd to vieldingly engage one terminal of" a fuse, and means for adjusting the fuse-engaging surfaces oi each oi said contacts toward and awav from each other to accomm'odate fuses having terminals of different thickness.

3. A fuse-carrying device comprising a pair of Fuse-carrying elements, each element comprising a pair of plates arranged side by side and adapted to receive one terminal of a luso between them, means for adjusting said plates toward and away from each other, and means for adjusting said contact elements toward and away from each other.

i. A use-carrying device comprising a pair of fuse-carrying elements, each element consisting 0i a pair of flat plates arranged parallel to each other and adapted to receive between them one terminal oi' a fuse, means for adjusting the plates of each carrying element relatively to each other, and means for adjusting the pairs of plates relatively to each other.
